ADDITIONS AND CORRECTIONS. 



Page 18, line 4 from the top : "1. In the T. longipalpi, the auxiliary vein 

 ends in the first.longitudinal, etc." In the genus Pachyrrhina the aux- 

 iliary vein, Immediately before its termination in the first longitudinal, 

 often has a stump of a vein, which, in some species, almost looks like a 

 cross-vein, connecting it with the costa. 



Page 19, line 14 from the top : " The Tip. longipalpi usually keep the wings 

 divaricate in repose," etc. Pachyrrhina and even some Tipuhe, keep the 

 wings folded in repose. The rule is less general than has been stated 

 by former authors. 



Pages 88, 89, 90 : In the three Latin diagnoses on these pages, read " venula 

 transversa" instead of "transversalis." 



While this volume was in press, two new species, Goniomyia manca and 

 Erioptera forcipula, have been added to it. The numerical data on pages 

 35 and the following were printed before this addition was made, and 

 have to be modified accordingly. The abnormal character of one of these 

 species, Goniomyia manca, requires that it should be quoted along with the 

 genus Cladolipes (on page 24 and in the third foot-note on page 44), as gn 

 instance of an exceptional disappearance of one of the branches of the 

 second longitudinal vein. For the same reason, on page 25, line 5 from 

 the top, instead of "in Goniomyia,''^ read "in Goniomyia manca." 



On the same page, 25, the genus Parafropesa Schiner (compare page 132) 

 may be quoted as forming an apparent transition between the TipuUdce 

 with one and those. with two submarginal cells. It has a cross-vein in 

 the marginal cell, which might be taken for a branch of the second vein, 

 if every other character did not point to a relationship with Teucholabis. 

 Hence I look upon it as having only a single submarginal cell, while Dr. 

 Schiner placed it among those with two such cells. Dr. Schiner's work 

 was received by me while this volume was in press*
